Effect of compositional ordering on the hysteretic magnetic properties of a cobalt-based amorphous alloy

详细

An investigation of Co₆₉Fe_3.7Cr_3.8Si_12.5B₁₁ amorphous alloy shows that thermally reversible isotropic short-range compositional ordering and clustering can lead to the degradation of hysteretic magnetic properties (HMPs). At temperatures below the Curie temperature (260°С), the degradation of HMPs is caused by thermally reversible directional ordering and reduces the mobility of domain boundaries. Clusterization, a thermally irreversible process observed via small-angle X-ray scatterimg, affects HMPs only during sample annealing immediately after quenching.
